oh haha, I am running the tekin RS... there is no need for the pro unless your planning to move to 4wd car in the future. As for my motor, I got the expressmotorsport d3.5 that has been outlawed, now I can't even race it at my track x_X But anyways, my bro has the tekin 7.5t gen2 and all has been running well with it.
Hope you have fun with your new kit
